Recessed Lighting Cost Calculator
Recessed lighting materials cost $25 to $135 per light in 2026, including an LED recessed kit, Romex wire, plus a shared dimmer switch and junction box. Basic disk LEDs start at $20 while trimless architectural fixtures reach $120+. Enter the number of lights below for a full itemized breakdown.
What materials do you need for recessed lighting?
Recessed lighting installation requires five materials: LED recessed light kits (one per light — modern kits include the housing, LED module, and trim in a single unit), 14/2 or 12/2 NM-B Romex wire (connects lights in a daisy-chain from the switch to each fixture), a dimmer switch (controls brightness — must be LED-compatible), a junction box (where the switch wire connects to the first light's circuit), and wire nuts or push-in connectors. For retrofitting existing ceiling lights, you may only need slim LED disk lights ($20-$35 each) that mount directly to the existing junction box — no housing required. A 6-light installation typically costs $180-$900 in materials depending on fixture quality.
How do you space recessed lights properly?
Proper spacing prevents dark spots and over-lighting. The general rule: divide the ceiling height by 2 to get the maximum spacing between lights. An 8-foot ceiling means lights no more than 4 feet apart. Place lights 2-3 feet from walls to create wall-washing effects that make rooms feel larger. For kitchens, space lights 3-4 feet apart in rows centered over countertops and the island. For living rooms, wider spacing of 5-6 feet works since ambient lighting is the goal. For hallways, center a single row with lights 4-5 feet apart. Always draw a layout before cutting ceiling holes — moving a recessed light after cutting means a drywall patch and repaint.
What size recessed light should you choose?
Recessed lights come in three common sizes: 4-inch (best for accent lighting, under cabinets, and tight spaces — produces a focused beam), 6-inch (the standard for general residential lighting — provides broad, even illumination and is the most commonly stocked size at retailers), and 8-inch (for high ceilings 10+ feet and commercial spaces). For most homes with 8-9 foot ceilings, 6-inch fixtures are the default. If your ceiling is 10+ feet, consider 6-inch with a higher lumen output rather than 8-inch, which can look oversized. Color temperature also matters: 2700K (warm white) for living spaces, 3000K (bright warm) for kitchens and bathrooms, and 3500-4000K (cool white) for garages and task areas.
